Gay me- straight roommate (HS friend)?

He knows I'm gay and probably he too knows that I have a feeling for him. He's a high school friend. And since I'm extra ordinarily nice to him like cooking for him and. Asking whether or not he's tired or what have you, so probably he knows that i'm in love with him. He's super cool about me being gay,he even gets excited. But now he's givin me the cold shoulder. Is he just trying to help me move on, or is it because he's uncomfortable with me? It's awkward because we have the same friends. And it feels like **** being ignored by the person you have feelings for and the one you live together with. Just curious, what would you guys do if you're in my shoes?
